Pin #
Name
Function
1
BOOT
HS Driver Supply.
Connect through a capacitor (100nF) to the floating node (LS-Drain) pin
and provide necessary bootstrap diode from VCC.
2
UGATE
HS Driver Output. Connect to HS mosfet gate.
3
GND
All internal references, logic and drivers are connected to this pin.
Connect to the PCB ground plane.
4
LGATE
LS Driver Output. Connect to LS mosfet gate.
5
VCC
Device and LS Driver power supply.
Operative range from 4.1V to 13.2V. Filter with at least 1
μ
F MLCC to GND.
6
FB
Error Amplifier Inverting Input.
Connect with a resistor R
FB
to the output regulated voltage. Additional
resistor R
OS
to GND may be used to regulate voltages higher than the
reference.
7
COMP / DIS
/ OC
COMP
. Error Amplifier Output. Connect with an R
F
- C
F
// C
P
to FB to
compensate the control-loop.
DIS
. The device can be disabled by forcing this pin lower than 0.5V(typ). To
disable the device, the external pull-down need to overcome 10mA of
COMP output current for about 15
μ
s. Once disabled, COMP output current
drops to 20
μ
A.
OC.
Over current threshold set. Connect with an R
OCSET
resistor to VCC
(ONLY IF VCC is supplied by 5V bus) to program OC threshold. When
VCC > 5V, R
OCSET
need to be not-connected.
8
PHASE
HS Driver return path, current-reading and adaptive-dead-time monitor.
Connect to the LS drain to sense R
dsON
drop to measure the output
current. This pin is also used by the adaptive-dead-time control circuitry to
monitor when HS mosfet is OFF.
